Verified
Most of the ventricle filling occurs ________.
A) during atrial systole
B) when the AV valve is closed
C) during ventricular systole
D) during atrial diastole
E) during isovolumetric contraction
AV Valve
Atrioventricular valves, which are located between the atria and ventricles of the heart, preventing backflow of blood from the ventricles into the atria.
Atrial Systole
The contraction of the atria chambers of the heart, which pushes blood into the ventricles.
Ventricular Systole
The phase of the cardiac cycle in which the ventricles contract, pumping blood out of the heart to the lungs and the rest of the body.

Final Answer :
D
Explanation :
Most of the ventricle filling occurs during atrial diastole, which is when the atria are relaxed and blood flows passively into the ventricles. This phase accounts for the majority of ventricular filling before the atrial systole contributes to the final part of filling.
